Hate to sound like a "glass-half-empty" type, but as we're passing the three-quarters mark of the first year of the rocky life of the TouchPad, I have to begin thinking about the max number of charge cycles the TouchPad battery can support before it gives up. Any engineering-types have insights?

It wouldn't just stop working it would slowly start to lose capacity.

Art imitates (my) life.
There hasn't been many posts about batteries going. I can't think of one, actually. So, 3/4 into the year, things look good.

Dr Battery (Homebrew) is available for the Touchpad now, and can give you an indication of your battery's health. Mine indicates 94% of new capacity.

As a tip to help prolong your battery, try and not to let it sit on the charger all the time at full charge. Also, if you plan to store it away for a long time, run the battery down to 40% first and put the TP in a cool place.

That's a big site with a ton of useful information. On the page you linked to, he mentions wireless chargers,(touchstone), he mentions 20-30% loss of energy through heat and that wireless charging stresses a battery. I didn't know that.

I would however, like to point out that I (according to Dr. Battery) have lost 0 percent in battery capacity from when I first bought my touchpad (still at 94 pct health) and my touchpad tends to live on my touchstone except for the days I bring it to school and when Im using it at home.

Enjoy your device, the more you stress about it losing capacity the less you enjoy it. True you could store it at 40pct and the correct temperature and the battery would last longer but you could never use it.

Dont Panic!

Bought mine 15 July 2011. Currently my 6612 mAh battery is at 91% with 6017 mAh left. I use mine relatively heavy, it comes with me daily to work(freeTether all day that I'm not at home), and I usually wind the battery down to next to nothing daily. I tend to throw it on a wall charger when I get home, so that it charges faster for evening use, and it's on a Touchstone all night until morning. I'm not too worried about battery life at this time.

Chances are good your battery will outlast the usefulness of your Touchpad. There are teardown instructions available if you can find a replacement battery to stash away. Even when they start losing capacity, it usually just means you have to charge them more often. I have some very old phones with Lithium Ion batteries that still power on and hold a charge.

I read 1,000 charge/discharge cycles somewhere.

My TouchPad is on its Touchstone when it's not in my hands and after almost 14 months the battery health is still 93% (was at 94% brand new), so much for the theory that Touchstones are bad for the battery.

I don't remember what my battery capacity was out of the box, but it's at 94% right now (was lower before I Doctored, so don't know what's up with that). The total capacity displayed by Dr. Battery is actually higher than what's rated on the label, and even at 94% the current rating is higher than on the label.

After 15 months of use, using the charging stand every other day, my Touchpad is at 93%. It did experience a freaky battery drain last night and wouldn't start this morning, but it came back to life with the power & home button trick. Aside from that I get two days of moderate use on a full charge.
